SWINGING-SASH HANGER.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed January 26, 1916. Serial No. 74,306.

To all whom it may concern Be it known that I, EDWARD J. FELLMAN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented cer tain new and useful Improvements in Swinging-Sash Hangers, and do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in hinged hanger devices adapted particularly for screen or storm sashes, although various features of the invention may find application in other connections.

It is primarily the object of the present invention to provide a han er device wherein the suspension plates carried by the sash may be readily engaged or disengaged with the hook members of the frame. A common disadvantage encountered in structures of this character which provide for ready manipulation to remove or detach the sash is that accidental disengagement of the sash may occur due to an upward and outward pressure being exerted on the sash by the wind or by any other cause, and it is therefore also an object of the present invention to provide a suspension device wherein the sash member is adapted for detachment only after being swung outwardly of a certain limit of movement, this limit of movement being the outermost position in which the various link members commonly employed in 1 the present connection are adapted for'holding the sash, so that in normal held positions of the sash by such link members disengagement of the hanger elements is impossible.

A further object resides in the provision of a hook member for the present device adapted to be stamped from a single sheet of metal and having its parts so arranged as to provide maximum strength and to prevent any accidental distortion of the hook member which might interfere with its function of holding the sash in the manner heretofore described.

A still further object resides in the provision of compensating means associated with the engaging portions of the hook and hanger plate members of the device wherein variations in the spaces between the respective hanger device elements carried by the sash and the window frame and due to ex- 1 pansion or contraction of the body of the sash or frame may be compensated for to provide for ready engagement of respective hook and suspension plates without procuring an undesired looseness of parts in the final assembled position.

WVith the above and other objects and advantages in view, the invention resides more particularly in the novel combination, arrangement and formation of parts more particularly hereinafter described and particu larly pointed out in the appended claims.

In the drawings: Figure 1 is a vertical sectional view through a hanger unit embodying the present invention. Fig. 2 is a front elevation of the improved hanger unit. Fig. 3 is an elevational view of the upper portion of a window frame and screen sash and showing a pair of improved units associated therewith with the bill portions of their hooks broken away to more clearly disclose the structure utilized to compensate for possible expansion or contraction of the sash or frame member. Fig. 4 is a top edge view of the hook member. Fig. 5 is a top edge view of a slightly modified form of the hook member. Fig. 6 is a plan view of the blank from which the hook member of the device is formed.

Referring now more particularly to the accompanying drawings, 5 designates a window frame and 6 designates a screen sash with which, and with the window frame the present hanger units are associated. Each unit comprises a hook member and a suspension plate detachably associated therewith.

Each of the improved hook members is formed of a single plate of material which is bent on a transverse central line and has its end portions bent laterally in parallel relation to thus form a hook body 7 and attaching wing portions 8. The top edge of the plate is provided on each side of its centrally bent line with cut-away portions 9 which when the plate is bent aline to form the hook, and the bottom edge of the intermediate portion of the plate is cut away at 10, whereby the bottom of the hook thus formed is spaced above the bottom edge of the wing 8.

Each suspension member comprises a plate 11 which is adapted to be secured to the upper corner of the sash, with its upper end projecting above the sash, and this upper end is offset outwardly and is provided with a longitudinal slot 12 which is of a length equal to the vertical width of the hook at diverged apart upwardly,

its bight and which has its sides taperingly the width of the slot at its lower end being substantially the width of the hook member. This shape of slot compensates for variations in the distance between respective hook members with respect to corresponding suspension members in the initial engagement of the hook and suspension members without procuring any undesired looseness in the final assembled position, for it is noted that upon swinging the plate inwardly after the insertion of the hooks through the slots 12 of the suspension members, the bottom portions of the hooks will abut the sides of the bottoms of theslots irrespective of whether or not relative expansion or contraction of the sash or frame members has occurred.

As shown in dotted lines in Fig. 1 the normal maximum outward inclination at which the sash member is adapted to be held by its usual link braces is at'an angle of sixteen degrees, and to prevent upward pressure on the sash or possible disengagement of the hook and suspension members at this inclination or at any lesser inclination, the inner bottom edge portion of the hook member forms an abutting surface 13 which is curved coincident with an arc of a circle having as its center the pivotal axis of the suspension plate when swung on the hook whereby in whichever position the sash is disposed within its aforementioned limit of pivotal movement, the bottom edge of the slot 12 will squarely abut this surface 13. Outwardly of this abutting surface 13 the bottom of the hook extends at an acute angle to said surface to provide a cam surface 14 whereby when the sash is swung outwardly of the aforementioned limit of movement at which the links hold it, upward pressure on the sash will cause the inner edges of the slots 12 to engage the surface 1 L whereby a camming action is procured which assists in detachment of the sash entirely from the hooks. To procure these faces 13 and 14, it is noted that a relatively wide V-shaped slot is formed in the bottom portion of the hook plate blank and opening into the cut away portion 10, with its apex lying in the bending line of the plate.

In the first four figures of the drawings, the hook member is shown as formed of a plate of relatively thick material which when bent to provide a contacting relation of its parts, provides for a sufficient trans- Copies of this patent may be obtained for verse width of the hook portion, but in some instances it might not be desirable to use a plate of such width as to procure the entire transverse width of the hook portion and in such instances the modified form shown in Fig. 5 is utilized wherein the material is bent in U-shape to provide a hook portion 7* having its sides spaced to procure proper transverse width.

The specific formation of the hook portion provides for a maximum strength, as the strain is imparted longitudinally of a portion of the metal plate instead of transversely of said portion, and this formation also prevents accidental distortion of the hook bill which might interfere with its operation in the various functions herein enumerated. A further advantage derived from this form of hook member is the resulting economy of material in stamping.

I claim:

1. A suspension device for outer sashes comprising a pair of curement to a support and a pair of plates adapted for securement to a sash to extend thereabove and provided in their upper portions with longitudinal slots each having its side edges diverged, the bight portions of the hooks being of a height substantially equal to the length of the slots and of a width equal to the width of the reduced ends of the slots.

2. A suspension device for outer sashes comprising a pair of hooks adapted for securement to a support, a pair of plates adapted for securement to a sash to extend thereabove and provided in their upper portions with longitudinal 'slots each having its sides diverged, the height of the bight portions of said hooks being substantially equal to the length of the slots and the width of the hooks being substantially equal to the width of the narrowest portions of the slots, and the inner portion of the bottom of each hook being curved substantially coincident with the are of pivotal movement of the adj acent edge of the slot.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of \Visconsin, in the presence of two witnesses.
